Purchased as an alternative to prototype springs used underwater. The price was reasonable and the delivery was quick and I was saved.
However, I had a hard time finding the target spring. I want you to increase the number of search items although there are various kinds. (Spring constant order etc) Since the original TRUSCO page was easier to find, I found this item after searching there.

Although it could be used without problems, I mistook the wire diameter when purchasing, I am worried about the strength a bit. I would like to purchase again if there are things with exactly the same shape and linearity 0.7 mm or more.
